What is Gonak Hypromellose?
Hypromellose is sometimes called hydroxypropyl methylcellulose.
Gonak Hypromellose (for the eyes) is used as an eye lubricant to treat dry irritated eyes.
Gonak Hypromellose is also used during certain eye surgeries to help maintain the shape of the eye, and to protect the tissues of the eye from injury during the procedure.
Gonak Hypromellose is also used during certain eye examinations to protect the cornea (the protective front layer of your eye), and to help determine whether fluid is properly draining from the eye.
Gonak Hypromellose may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

How should I use Gonak Hypromellose?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
